Changing the choice for dialysis to conservative care or vice versa in older patients with advanced chronic kidney disease

Exploring the unmet needs and experiences of informal caregivers of patients with end-stage kidney disease (ESKD) receiving haemodialysis - a qualitative study

BACKGROUND

Patients with end stage kidney disease (ESKD) receiving haemodialysis experience multiple symptoms, which can present physical and emotional challenges for both patients and their informal caregivers. Caregivers can experience anxiety, depression, and social isolation negatively impacting their overall wellbeing and resulting in caregiver burden. The needs of this group of caregivers have been largely neglected, with little emphasis placed on supportive interventions that might assist and support them in their caring role.

AIM

The aim of this study Is to explore the unmet needs and experiences of caregivers of patients with ESKD receiving haemodialysis, and to determine the components of a supportive intervention.

DESIGN

A qualitative study using semi-structured interviews (n = 24) with informal caregivers. An interpretive qualitative framework was employed to generate a rich understanding of the unmet needs and experiences of caregivers. Data was analysed using thematic analysis. Interviews were transcribed verbatim and data management was assisted through NVIVO version 11.

SETTING/PARTICIPANTS

Twenty-four informal caregivers were purposively recruited from two haemodialysis settings within Northern Ireland.

RESULTS

Three themes were identified: (1) The negative impact of distress, anxiety, and isolation on caregivers due to their caregiving responsibilities (2) Inadequate information and knowledge about the complexities of renal care (3) The benefits of spiritual beliefs, stress management and peer support in relieving the caregiving burden.

CONCLUSIONS

Caregivers of patients with ESKD receiving haemodialysis are at increased risk of physical and psychological distress and burden arising from their caregiving role. The unpredictable nature of ESKD and haemodialysis treatment negatively impacts the caregiver experience and adds to the challenges of the role. The information needs of caregivers are not always adequately met and they subsequently lack appropriate knowledge, skills, and guidance to assist them in their caregiving role. Supportive interventions are essential for caregivers to enhance their capability to deliver effective care and improve their quality of life.

Choosing conservative care in advanced chronic kidney disease: a scoping review of patients' perspectives

BACKGROUND

Conservative care (CC) is a viable treatment option for some patients with kidney failure. Choosing between dialysis and CC can be a complex decision in which involvement of patients is desirable. Gaining insight into the experiences and preferences of patients regarding this decision-making process is an important initial step to improve care. We aimed to identify what is known about the perspective of patients regarding decision-making when considering CC.

METHODS

PubMed, EMBASE and Cochrane databases were systematically searched on 23 February 2023 for qualitative and quantitative studies on patient-reported experiences on decision-making about CC. Data were analysed thematically.

RESULTS

Twenty articles were included. We identified three major themes: creating awareness about disease and treatment choice, decision support and motivation to choose CC. Patients were often not aware of the option to choose CC. Patients felt supported by their loved ones during the decision-making process, although they perceived they made the final decision to choose CC themselves. Some patients felt pressured by their healthcare professional to choose dialysis. Reported reasons to choose CC were maintaining quality of life, treatment burden of dialysis, cost and the desire not to be a burden to others. In general, patients were satisfied with their decision for CC.

CONCLUSIONS

By focussing on the perspective of patients, we identified a wide range of patient experiences and preferences regarding the decision-making process. These findings can help to improve the complex decision-making process between dialysis and CC and to provide patient-centred care.

Comprehensive conservative care: what doctors say, what patients hear

The demographic evolution of patients with advanced chronic kidney disease (CKD) has led to the advent of an alternative treatment option to kidney replacement therapy in the past couple of decades. The KDIGO controversies on Kidney Supportive Care called this approach "comprehensive conservative care" (CCC) and defined it as planned holistic patient-centered care for patients with CKD stage 5 that does not include dialysis. Although the benefit of this treatment option is now well-recognized, especially for the elderly, and comorbid and frail patients, its development remains limited in practice. While shared decision-making and advance care planning represent the cornerstones of the CCC approach, one of the main barriers in its development is the perfectible communication between nephrologists and patients, but also between all healthcare professionals involved in the care of advanced CKD patients. As a result, a significant gap has opened up between what doctors say and what patients hear. Indeed, although CCC is reported by nephrologists to be widely available in their facilities, few of their patients say that they have actually heard of it. The objectives of this review are to explore discrepancies between what doctors say and what patients hear, to identify the factors underlying this gap, and to formulate practical proposals for narrowing this gap in practice.

Shared decision making: a personal view from two kidney doctors and a patient

Shared decision making (SDM) combines the clinician's expertise in the treatment of disease with the patient's expertise in their lived experience and what is important to them. All decisions made in the care of patients with kidney disease can potentially be explored through SDM. Adoption of SDM in routine kidney care faces numerous institutional and practical barriers. Patients with chronic disease who have become accustomed to paternalistic care may need support to engage in SDM-even though most patients actively want more involvement in decisions about their care. Nephrologists often underestimate the risks and overestimate the benefits of investigations and treatments and often default to recommending burdensome treatments rather than discussing prognosis openly. Guideline bodies continue to issue recommendations written for healthcare professionals without providing patient decision aids. To mitigate health inequalities, care needs to be taken to provide SDM to all patients, not just the highly health-literate patients least likely to need additional support in decision making. Kidney doctors spend much of their time in the consulting room, and it is unjustifiable that so little attention is paid to the teaching, audit and maintenance of consultation skills. Writing letters to the patient to summarise the consultation rather than sending them a copy of a letter between health professionals sets the tone for a consultation in which the patient is an active partner. Adoption of SDM will require nephrologists to relinquish long-established paternalistic models of care and restructure care around the values and preferences of patients.

Ageing meets kidney disease

Chronic kidney disease (CKD) is defined as abnormalities of kidney structure or function, present for >3 months, with implications for health. The most used diagnostic criteria are a urinary albumin: creatinine ratio ≥30 mg/g or an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2. Either of these diagnostic thresholds is associated with adverse health outcomes. GFR decreases with age and the prevalence of CKD is highest in older adults; moreover, the presence of CKD is associated with an increased risk of all-cause and cardiovascular death related to accelerated ageing in all age ranges, and the absolute increase in risk is highest for those aged >75 years. Indeed, premature death is a more common outcome than CKD progression to kidney failure requiring kidney replacement therapy. The progressive ageing of the world population contributes to the projection that CKD will become the second most common cause of death before the end of the century in countries with long life expectancy. The current collection of selected studies on kidney disease and ageing published in Age&Ageing, NDT and CKJ provides an overview of key topics, including cognitive decline, sarcopaenia, wasting and cardiovascular and non-cardiovascular morbidity and mortality, the management of kidney failure and gender differences in CKD progression.

Background

Non-dialytic conservative care (CC) has been proposed as a treatment option for patients with kidney failure. This systematic review and meta-analysis aims at comparing survival outcomes between dialysis and CC in studies where patients made an explicit treatment choice.

Methods

Five databases were systematically searched from origin through 25 February 2021 for studies comparing survival outcomes among patients choosing dialysis versus CC. Adjusted and unadjusted survival rates were extracted and meta-analysis performed where applicable. Risk of bias analysis was performed according to the Cochrane Risk Of Bias In Non-randomized Studies of Interventions.

Results

A total of 22 cohort studies were included covering 21 344 patients. Most studies were prone to selection bias and confounding. Patients opting for dialysis were generally younger and had fewer comorbid conditions, fewer functional impairments and less frailty than patients who chose CC. The unadjusted median survival from treatment decision or an estimated glomerular filtration rate <15 mL/min/1.73 m² ranged from 20 and 67 months for dialysis and 6 and 31 months for CC. Meta-analysis of 12 studies that provided adjusted hazard ratios (HRs) for mortality showed a pooled adjusted HR of 0.47 (95% confidence interval 0.39–0.57) for patients choosing dialysis compared with CC. In subgroups of patients with older age or severe comorbidities, the reduction of mortality risk remained statistically significant, although analyses were unadjusted.

Conclusions

Patients opting for dialysis have an overall lower mortality risk compared with patients opting for CC. However, a high risk of bias and heterogeneous reporting preclude definitive conclusions and results cannot be translated to an individual level.
